AR随机过程的建模，给定一个AR过程，对其进行建模，分别利用Yule-Walker方程和协方差法进行功率谱估计(AR random process modeling, given an AR process, its modeling, respectively, Yule-Walker equations and covariance method of power spectrum estimation)

最优化方法的一些基本算法的实现：1，0.618法；2，牛顿法；3，改进牛顿法；4，FR法；5，DFP法(Ways to optimize some of the basic algorithm implementation: 1,0.618 method 2, Newton' s method 3, improved Newton method 4, FR Act 5, DFP method)

这是一个用matlab编写的人脸搜索程序里面包含一个小的人脸图片数据集。(This is contains a small face images datasets were prepared using matlab face a search program inside.)

这个文档包含四种不同的功能求解非线性方程组。包括牛顿 - 拉夫逊，定点，正割，二分法方法。这项工作是我的课程的一部分，在数值计算的本科课程。它包括时序和表的打印输出进行分析和比较。有很多的观察，你可以：例如，对于一个特定的公式，一种方法可能运行的迭代次数最少，而另一个将运行更多的迭代，但计算速度最快的。(This document contains four different functions for solving nonlinear equations. Including Newton- Raphson, fixed, Secant, bisection method. This work is a part of my course in numerical undergraduate courses. It includes the timing and tables to analyze and compare the printout. There are a lot of observation, you can: For example, a specific formula, a method may be running a minimum number of iterations, while the other will run more iterations, but the calculation is the fastest.)

说明：  火焰图像检测的matlab程序，含有多种检测方法，可直接运行(The matlab program of flame image detection contains many detection methods, which can be run directly)

PCA算法Matlab实例，有详细的中文注释(PCA algorithm Matlab examples detailed Chinese Notes)

我学习信号系统时原创的用matlab实现的谐波提取 ，两种方案，先分频再提基波，或者利用带通滤波器(I study the signal system to achieve an original harmonic extraction using matlab, the two programs, the first frequency and then Ti Jibo, or the use of band-pass filter )
